Method for interplanting trifolium repens in fruit forest

Abstract

The invention provides a method for interplanting trifolium repens in a fruit forest. The method is specifically characterized by including the steps of firstly, sowing trifolium repens seeds in strips between lines of fruit trees in March in the Gregorian calender; secondly, conducting after-sowing management, wherein harvesting starts when the trifolium repens reaches the height of 30 cm, stubbles are not lower than 5 cm, the harvested trifolium repens is buried under the fruit trees on site, the trifolium repens can be harvested 3-4 times every year, the trifolium repens has to be harvested1 month before fruit picking in the fruit forest so that fruit coloring can be promoted, and a pesticide is sprayed to a lawn in combination of fruit tree disease and pest prevention and treatment inthe last ten days of May in the Gregorian calender every year. By interplanting the trifolium repens in the fruit forest and fixing nitrogen in air through the trifolium repens, only a phosphorus-potassium fertilizer needs to be applied to the fruit trees in the fertilizer applying process, and a nitrogen fertilizer is saved; by planting the trifolium repens, the growth of other weeds is restrained, and the effects of improving soil and improving soil fertility are achieved; a virtuous circle ecological system is formed by the fruit tree.

Description

technical field [0001] The invention belongs to the field of fruit tree planting, and relates to a method for interplanting white clover in fruit forests. Background technique [0002] At present, in the planting of fruit trees, forests are formed by species, and weeds are overgrown in the fruit trees, and labor costs are wasted for weeding; in addition, nitrogen, phosphorus and potassium compound fertilizers must be continuously supplemented during the growth of fruit trees, and the cost of fertilization is high. [0003] White clover is a leguminous clover plant with a large number of nodules on its taproot and lateral roots, which can fix nitrogen in the air. Contents of the invention [0004] The invention proposes a method for interplanting white clover in the fruit forest, which not only restrains the growth of weeds in the fruit forest, but also provides nitrogen for the fruit trees, and does not need to use nitrogen fertilizer in the growth of the fruit trees.
